I highly recommend stacking 4ad with it, your body will thank you for it.

I really think 10mg m1t will be plenty for 4 weeks. I just came off a similar 4-weeker & I to increased to 20mg M1t (from 10mg) in week 3. My gains did not increase, only cramping & lethargy did. I dropped back to 10mg in week 4. I am 6' & a decently lean 225 lbs, I won't go over 10mg anymore. If you are still gaining after 2 weeks, which I'm sure you will be- why increase the dose?

Your PCT looks good. I usually stay off creatine on cycle, it helps maintain bodyweight if I go back on it during PCT.
